Software for robust statistics

ROBETH

ROBETH is the program library for robust statistical procedures described in the book entitled "Algorithms, Routines and S-Plus Functions" by A. Marazzi (Wadsworth and Brooks/Cole, 1993; reprinted by Chapman Hall). ROBETH has been interfaced to the statistical environments S-Plus and R.
Several errors in ROBETH and in the book have been corrected and a few changes have been made. The most recent version of ROBETH and a list of corrections are made available here.
